Ecological grit

“Eco grit”, also widely known as "Copper Slag", is a mineral abrasive used for treating surfaces. It can be used as a replacement of sand blasting, which is very well known for causing extremely high rates of silicosis and lung cancer among workers and staff in the surroundings.

  • Why replace the sand for surface preparation?

Although sand is the most widely available and economical natural abrasive, there are many reasons why sand blasting/hydro blasting should be eradicated and prohibited: when the sand is projected on a surface, most of it turns into dust in sizes smaller than 300Mesh because of the impact.

The environmental pollution generated in the workplace and nearby areas is composed of free silica, which is the main cause of silicosis, a disease that causes breathing difficulties and subsequent death to a very high percentage of the staff involved in these tasks.

For these reasons, security requirements have been multiplied and they have caused the ban of sand blasting in most of the technologically advanced countries.

  • CSA Ecological Grit
